Definitions

  • a component package including elements such as an integrated circuit "chip"
  • Such packages frequently comprise "active" elements affixed to a base across which conductive circuitry extends from one or more of the elements to connector prongs oriented substantially parallel to each other and at right angles downward from the bottom of the base of the package.
  • Such component packages may thereby be interconnected with other circuit components by thrusting the connector prongs into position between spring loaded receptacle contacts.
  • the voltages and currents involved in such applications are small, so it is desirable and usually necessary for the pressure exerted by the spring-like receptacle contacts on the exterior of the package prongs to be very high in order to ensure that effective electrical interconnection is achieved.
  • the component package is fragile and the connector prongs extending downward from the base of the package also are relatively fragile, both are rendered highly susceptible to bending, breakage and other derogatory effects, particularly when an attempt is made to remove the package from the receptacle against the strong retention forces of the receptacle contact elements.
  • Various mechanisms have been proposed for use with receptacle devices to circumvent these problems, but typically they tend to be complex structurally and mechanically, and therefore costly to construct and to occupy circuit board surface that might otherwise be utilized to greater advantage.
  • Another object of this invention is to produce such means wherein removal of such packages therefrom will be facilitated.
  • Still another object of this invention is to produce such means wherein such removal may be accomplished without objectionable derogatory effect to the component package or the prongs projecting from the bottom of the package.
  • Yet another object of this invention is to provide such means in a form and structure which will be mechanically simple and relatively inexpensive to construct and operate.
  • Another object of this invention is to provide such means in a form which will permit greater utilization of available circuit board surface.
  • Desired objectives may be achieved through practice of the present invention which, in one embodiment, comprises a printed circuit board receptacle for the contact prongs of dual in-line packages wherein said receptacle has either contacts, or prong backing surfaces, or prong guides which are movable laterally at right angles to the direction of insertion of the package prongs, whereby, through such movement, prongs residing in slots described by contacts and associated backing surfaces, may be disengaged from each simultaneous contact with both a contact and a backing surface, thereby freeing the package for easy removal from the receptacle.
  • FIG. 1 is a cross-sectional view of a printed circuit board receptacle of the type herein contemplated, with an associated dual in-line component package in place,
  • FIG. 2 is a perspective view of an embodiment of this invention
  • FIG. 3 is a plan view of a portion of the embodiment of this invention shown in FIG. 2,
  • FIG. 4 is a side view of the portion of this invention shown in FIG. 3
  • p FIG. 5 is another perspective view of the embodiment of this invention shown in FIG. 2,
  • FIGS. 6a and 6b depict another embodiment of this invention
  • FIG. 7 depicts another embodiment of this invention.
  • FIG. 8 depicts another embodiment of this invention.
  • FIG. 9 depicts another embodiment of this invention.
  • FIG. 10 depicts another embodiment of this invention.
  • FIG. 1 there is depicted a cross-section of a printed circuit board receptacle (1) for so-called “dual in-line” component packages. As illustrated, it comprises sidewalls (2) in which are positioned receptacle connector contact elements (4) which extend downward through holes (6) in an associated printed circuit board (8) for interconnection, as by soldering or other appropriate means, with conductive paths (9) on the printed circuit boards.
  • the contacts (4) present an angled contact point (7) to the surface of the connector prongs (5) of an associated component package (3), in order to ensure a reduced area and high unit area pressure, to achieve effective electrical contact therebetween.
  • FIG. 2 depicts an embodiment of the present invention for electrically interconnecting the contact prongs (24) of a circuit component "package" (26) with receptacle contact clips (22) having contact edges (23), which clips (22), together with corresponding backer surfaces (25), form slots into which prongs (24) may be inserted.
  • the backer surfaces (25) are illustrated in FIG. 2 as planar plateaus, they might be of any of a variety of other shapes such as domes, semi-cylinders, linear arrays, etc.
  • the receptacle contact clips (22) which have tail portions (14) extending through holes (16) in a printed circuit board (18) so as to interconnect with conductive paths (not shown) on the printed circuit board.
  • FIG. 2 has a main receptacle body (30) to which are affixed one or more arrays of contacts (22), on top of which is positioned a receptacle member which, in this embodiment, is in the form of a slideable cover (32).
  • the main body includes a tool port (31) formed integrally therewith for the purposes hereinafter described. Since, as shown in FIG.
  • the clips (22) are arrayed in straight linear arrays, one along each edge of the main body (30), so that they will correspond to the prongs (24) of the package (26), the cover (32) includes corresponding linear arrays of apertures (34) through which the prongs (24) may be inserted into the slots in concurrent juxtaposition with the bearing edges (23) of the contact clips (22), and the backer surfaces (25).
  • the term "linear array” is not intended to imply any limitation to the arrays being in straight lines as shown in FIG. 2.
  • the receptacle contact array might be circular and the cover circularly movable with respect thereto, for the purposes hereinafter described.
  • the apertures (34) are depicted in FIG. 2 as being completely surrounded by cover material, it will be clear that it is not necessary for them to be so surrounded on all four sides.
  • the apertures might open to the outside of an edge of the cover (32), and if it is desired in such a case to protect the outside exposure of the prongs (24) after they have been inserted, the cover (32) may be surrounded by a bordering flange (not shown) at the top of the sides of the main body (30).
  • a bordering flange not shown
  • Biasing means in this illustration, in the form of cantilever springs (40) integral with the cover (32), acting cooperatively with partitions (42) integral with the main body (30), serve normally to bias the cover (32) into a position such that the apertures (34) are juxtaposed to the desired corresponding contacts (22).
  • FIGS. 3 and 4 are a plan view and a cross-sectional side elevation respectively, illustrating structure to ensure that the cover (32) and associated circuit component "package" (26) when correctly positioned cannot be moved inadvertently, as hereinafter described.
  • a latch (44) may be formed integrally with the cover (32) facing downward near one end, corresponding in position to a notch (46) formed in a cantilever spring (48) having a depressor tongue (50) at the end farthest from its point of connection (52) to the partition (42). From these illustrations, it will be apparent that the cover (32) may be made free to slide to the right upon depression downward of the tongue (50) of the beam spring (48), with consequent unlatching of the latch (44) from the notch (46).
  • FIG. 5 illustrates how the aforesaid embodiment of this invention may be used. It depicts a printed circuit board including a number of receptacles of the type herein described in FIGS. 2, 3 and 4. As has been discussed in connection with FIG. 1, the sharp, biting effect of the edge (23) of each contact clip (22) on the connector prong (24) associated with it, backed, as it is, by a backer surface (25), makes it difficult, if not impossible, to remove the circuit component "package" (26) without damaging the prongs.
  • a screwdriver (100) may be inserted into the tool port (31), until it impinges upon the tongue (50) of the lever arm (48), if one optionally has been employed, depressing the arm (48) downward so as to disengage the latch (44) on the cover from the notch (46) on the lower arm; the screwdriver (100) may then be pivoted to press upon the tool abutment (33), causing the cover (32) to slide horizontally in a direction perpendicular to the direction of insertion of the prongs (24).
  • each prong (24) may be caused to slide past the biting edge of the contact with which it is associated; all of the prongs being moved simultaneously, until each one is free from engagement with an associated contact.
  • circuit component package may then be freely and easily removed from the receptacle without objectionable effect on any of the prongs (24).
  • the associated bias means e.g., the beam spring (40) acting upon the partition (42) will cause the cover to move back to its original position, blocked against further lateral movement by the combination of cooperating latch (44) and notch (46), ready for receipt of the same or another circuit package.
  • connector arrays straight or arcuate, according to the configuration of the circuit "package" and the direction of relative motion between the cover and the main body of a given receptacle, may be positioned at various locations in the constituent parts of receptacles made in accordance with this invention.
  • FIGS. 6a and 6b depict another embodiment of this invention which is illustrative of this fact.
  • the receptacle (101) is round and comprises a receptacle member in the form of an outer, torsionally movable, cylindrical sleeve (102) which has prong receptacles (106) on its inner periphery and closely surrounds a main body (104).
  • the member (102) may be biased toward a position relative to the main body (104) such that the apertures (106) are juxtaposed to contact clips (not shown) of the type heretofore described that are affixed to the main body (104), by known per se means, such as a helical spring impelling the member (102) against a stop integral with the main body (104).
  • a circuit component package (110) may have its prongs (112) positioned in the apertures (106) to effect electrical connection therewith. Thereafter, when it is desired to remove the package, the member (102) may be moved torsionally to cause the prongs (112) to slide out of engagement with the contact prongs, substantially in the fashion of the relative movement effected in the embodiments previously described, permitting easy removal of the component package. It should be noted that embodiments such as this afford special advantages for overcoming factors such as "G" loads or other inertial effects without use of latching arrangements or other devices of the type heretofore described.
  • FIG. 7 illustrates the relative movement of these elements in the embodiments heretofore described; i.e.
  • the prongs (24) are moved laterally by a distance greater than that necessary to cause the prongs (24) to disengage from concurrent contact by both the clip (22) and the surface (25), whereupon the prong (24) may be easily removed in a direction opposite the insertion direction, or perpendicular or normal to the motion path of the movable cover member (32) and the prongs (24).
  • a comparable releasing effect may be achieved by moving the clip (22) relative to the prong (24) and backer surface (25), by a distance such that the clip (22) no longer bears on the prong (24), thereby releasing the prong for easy removal as described above.
  • the prong (24) and the clip (22) may be kept stationary, and the backer surface (25) moved laterally relative thereto. Since this will have the effect of relieving the pressure with which the prong (24) is held against the inherent spring bias of the clip (22), the prong (24) will be free to deflect slightly in the direction away from the clip, thereby permitting easy removal of this prong from contact with the clip.
  • Embodiments may be made incorporating any of a wide variety of known per se structural means for effecting motion of the backer surfaces and/or the contact clips to achieve the motion effects of the type described above.
